I have added Magelis Ethernet HMI's to my workcell that poll the PLC and have noticed a decrease in performance with increasing response time delays. How can I improve performance?

Implement a SCADA I/O Server. The IO server will be the only device to poll the PLC thereby reducing socket usage on the PLC. The HMI's can then poll the data from the IO server instead of multiple HMI's polling the PLC directly.
